The page he has linked is not a guide, but the site has a guide on it. If you don't understand what the things on the page he has linked are, I suggest you don't try it unless you research a lot and figure out what needs doing.

I put that there, and I can say right now, if you do not know what it means don't bother. It's there for developers as the DevTeam patches in PwnageTool are most likely not going to include everything that I patched, as they usually just do the standard codesign then w^x patch.
